Research Interests
My group’s research area includes classification and physical response of topological states, transport theory in disordered systems, correlation physics in topological materials, and other topics. Currently, I’m particularly interested in the strong correlation physics emerged in (topological) flat bands, exampled by twisted-bilayer graphene, and its interplay with the topology.

Opening Positions
I plan to recruit one PhD student each year, and currently have one opening for a postdoc researcher. Undergraduate students are also welcomed to join our researches.
